Description
Technical field
The utility model belongs to sludge modification technical field, and in particular to a kind of sludge modification curing process system.
Background technique
With the development of China's urban economy and the increase of population, China's water pollution is got worse, and is built at municipal sewage
Managing factory, oneself becomes the indispensable behave for administering water pollution.To late 1990s, national oneself builds up sewage plant more than 300
Seat, (sewage treatment capacity about 1.3x107m3/d).However, municipal sewage can generate a large amount of sludge during processing, wherein
The sludge quantity that primary sedimentation tank generates is about 0.2%~0.3% (moisture content is 95%~97%) for the treatment of capacity, and secondary settling tank excludes surplus
Remaining active mud content is 1%~2% (moisture content is 99.4%~99.6%) for handling water, one 100,000 tons for the treatment of scale
Sewage treatment plant excludes 200 tons~300 tons of first sludge, 1000 tons~2000 tons of residual active sludge daily.At waste water
The further genralrlization of reason technology and development and wastewater discharge standard it is increasingly stringent, the yield of sludge will be increasing.
Sludge components are complicated, are organic matter and inorganic matter composition that the zoogloea of multiple-microorganism formation is adsorbed with it
Aggregate also contains organic matter difficult to degrade, heavy metal, a small amount of except containing (up to 99% or more) in addition to a large amount of moisture
Pathogenic microorganisms (pathogenic bacteria, pathogen, helminth, harmful insect ovum etc.) and general oxygen-consuming organic matter and plant
Nutrient (N, P, K) etc..It is not added on processing disposition if be piled up arbitrarily, large amount of land resources, and the perishable change of sludge will be occupied
It is smelly, it generates percolate soil and groundwater easy to pollute and causes with the surface water bodies such as river, lake, ocean to environment serious
Secondary pollution.It also will affect environmental sanitation situation simultaneously and destroy urban landscape, cause the acceleration of water body deposit etc. and endanger.Separately
Outside, the heavy metal in sludge and toxic organic compound can by the food chain Migration And Concentration in the ecosystem, to ecological environment and
Human health generates long-term potentially hazardous.In addition to this, it is arbitrarily discharged into water body, sludge as stable processing is not added in sludge
In organic matter and ammonia, nitrogen by the oxygen in a large amount of consumption water bodys, cause water quality to deteriorate, seriously affect the life of aquatile
It deposits, the nutriment in sludge will cause the eutrophication of water body, promote the pernicious breeding of algae, cause the red tide and green tide of water body
Phenomenon not only deteriorates urban water resource water quality, influences domestic water and upper agricultural water, will also fishery production be made to decline, and caused
Huge economic loss.
Therefore, solve so a large amount of sludge outlet oneself become very urgent task.
